The four musicians of ‘NuMBq’ led by Michael Bisio puts a bit of a classical orchestra into their quartet of unbound adventurers.

Brian Groder has another go at it with his supercharged trio on ‘R Train on the D Line,’ creating the logical sequel to 2014’s ‘Reflexology.’

‘Reflexology’ continues with Groder’s open-ended mastery, with a rhythm section that acts as a natural extension of its leader.
